This may be. of any, appropriate constructi on and isadapted to conta n the movable parts of the. device. In the. instance illustrated it consists of aapastehoerd cyls indcr 1, which forms the sides walls of the a ing; and op and. m wa 2- 2 of sheet metal. I u

Within this casing is arranged a adapted to slide longitudinally of ns- Th weigh onsti ute t w e l head of a bellows the opposite member or head of the bellows being the bottom vvall 2 of the casing, and the bellows being corn; pleted by a softfleaible cylindrical niember 3 whi'ch connects said heads,

Weight Q The head; G has acentral open-i ing 4 by \vhieh it is slidabl y nounte upon a central rod 5, redo being in turn fixed, preferably by its opposite ends, to thecasing as by being received in pits fiforined in thewalls of the casing. a

The head G is it operates by gravity to listend and col lapse the bellows n'ien ber 3 henever the easing ism oved flgfilll an uptight to an inverted position and vice versa, and it thus automatically produces sounding of a need or like suitably sound producing" element 7 carried preferably by the head G.

Within the head is formed 1,121 W,- propriate sound box 8 with which the reed,

communicates through a suitable open-T ing 9. a

An opening 10 provided through the top wall member 11 o t." the sound box through which the sound waves from the reed and sound box must pass on their Way to the outer atmosphere, o i

The top wall as 2 9f the casing ispe terated in the usual manner in ordeljt hat the sound waves may pass freely out of the casing. i

The Wall lIlQIIItbGfll of the sound. boxis preferably formed of sheet metal. It is of inverted saucer shape and its lower an nular edge portion has telescopic engage..- ment with the annular edge portionof the head and serves not only to. hold these, two parts. in assembly but also to clampfthe upper annular edge portion of the bellows Isis the casof sufficient vveightso, that i member 3. in position upon the movable heed. i

The sound emitting opening 1 0 iseoncentrio with the opening 4 and the material of the. Wall 11 surrounding said opening isi 'a ly bent n er y a d wnwa ly so. as to.preventhornslike. ta 'iering walls 12 outwardly from said opening 10 outwardly through the, opening 10, .anfd to lows.

therebydetermine the operation. of the reed 7 and the inflections of the passing sound waves, the present invention utilizes the single separately formed valve member H mounted to move to and fro through the opening 10 during the operation of the bel- This valve member has a central bearing opening 13 by which it is slidably mounted upon the rod 5. v I

Aligned with the opening 10 the main portion of the head G is provided with the dash-pot 14: directly below said opening 10 and of a size to receive the valve H when said valve slides down the rod 5, the relation of the valve to the dash pot being such that the falling movement 01 the valve will be retarded to a suitable extent to properly time the valve movement in proportion to the movement of the head, in the same manner more fully set forth and described in the pending application above referred to. Carried by the main portion of the head G is a separately formed stop rod 15 which is arranged parallel with the rod 5 and which is adapted to slide freely through a bearing opening 16 formed in the head Cr beneath the valve H. It is provided with upper and lower shoulders 17 and 18 to prevent its disengagement from the head at all times.

As the head G, with the valve H, slides downwardly along the rod 5, the lower end of the rod 15' comes into engagement with the upper surface of the bottom wall 9. of the casing and the upper end of the rod 15 serves to support the valve H positively against further downward movement,

In the operation of the device, assuming the casing to have been just returned to an upright position after being inverted, the stop rod 15 will move downward through the opening 16 to the position indicated, the head G will begin to descend and the displaced air from beneath it will cause sounding of the reed. These initial waves, passing into the sound box 8, will issue there from in a much subdued manner through the opening 10. it being noted that at this time the valve H is standing within said opening and that the Valve is sufliciently smaller than said opening so 'as to leave a crevice as 19 between itself and the walls of the opening of just the right size to produce the desired result, that is the momentary purring or nasal sound mm. preceding. or lorininr.

the initial part of, the first syllable ot the word manna. I i

The valve H has also begun to slide down the rod 5. Except for the presence of the dash-pot 14 this valve would fall almost instantly out of the opening 10. The fall of the head G-is relatively slow because of the requirement for displacing air trom within the bellows, but the valve H has not this resistance to control with. It has merely the dash-pot 14: to overcome and its relation to this is just such as to properly timethe fall of the valve relative to the fall of the head G.

As the parts continue to fall, and the valve H finally drops out ottheopening 10 the sound waves will pass freely from. the sound box and produce the main portion of the first syllable of the word ma-ma.

During at least a part of this period the 'gagement against the bottomf wall of the casing and the valve H will be likewise brought to rest by being supported upon the upper end of the rod 15. V v

' The first syllable of the word ma-ma will be terminated by thus closing the opening 10, and a second purringon nasal sound min will result from the again restricted passage through which the sound waves must pass from the sound box.

As the head G fell away from the stationary valve H the dash-pot actionbetween the valve and the dash-pot 14 caused a reduction in the gravity pull of the head and the force, or draught, of air through the reed was inomentarily reduced just prior to the termination of the first syllable ma so that said syllable ended smoothly and merged gradually. into the purring or mm? sound with a desirable inflection of thesound waves.

The second, or mm sound will continue until the valve has again passed through thelopening 10, or rather until the headG has fallen, so that the opening has moved entirely free of the valve. As the dash-pot 14-. felliree of the valve the head suddenly resumed, its normal speed of descent and there waspresent for the moment an eXcess ofair pressure through the reed. This occurred at ainoment when the valve stood directly within the opening 10 and caused the purring nnn sound then issuing from the device to be momentarily intern'iediate, purring nov accentuated and thereby given a desirable and natural inflection closely approximating r the exasperated cry of an infant. V

The second or final syllable of the word fma-ma will begin to sound as the opening 10 passesbelow the lower edge of the valve and will continue so long as air continues to move through the reed,f.that is untilthe head G comes to rest in its lowermost position against the bottom wall'2 oi lllQCfiSlHQ.

By shaping the top wall member 11 of the i sound box with its port-ion forming' the opening 10 bent inwardly there is provided not only the outwardly flaring horn-likeportion 12 for gradually increasing the volume menus I accomplished among which"may be mientloned the factthatrthe lower end portion pocket 6.-= In thisway it serves not only to,

of the inturned part may be: Suitably extended to form a paralleliwalled tubular portion at the lower end: of the: horn-like portion 12. This tubular portion may." be given suitable vertical length to provide the desirediamount of resistance to the passage of air during the mm eriod s without requiring a too close fit of; tl ievalve therein Also it will provide a surface portion as. 21 which may engage against the inner surface of the top cover member 2 toglimit movement oi the head GtoWardsaid cover member and tothusaccurately delinethe position. otthe head (in preliminary toeach operation of the device, it being noted that i310 extreme-position of the valve H is limited by engagement with the same cover mei nbe'r, or against/ a cushion member 22 liked to snide-over member. i a The cushionmember as illustrated as interposed between the upper end surface of the rod 5 and the adjacentinner surface of the cover member?and cxtending into the cushion movements of the valve H against the cover member but it also constitutes a 50ft resilient filler between the cover member and the endof the rod and 110 thereby insure that said rod will be firi'uly held in position without necessity clor imposing any undue strains uponeither of the e-over members.

It has been the practice heretofore to makethe central standard or rod as 5 considcrably longer than the-normal distance between the im er suriiace.ot the opposite cover membersand then when assembling the device, to apply saidcover members by a force suflicient to cause the cover members to bow outwardlyand thus, accommodate the rod. By lirmly attaching the cover members ontothe opposite ends of the cylinder l'the bowed condition ofthe covers has been main tained and a suitable resilient grip thusappliedupon the rod so as tohold it firmly against rattling or dislodgen'ient from its appointed positioli. i It has not infrequently occurred however that the strain upon the connections between the cover members and the pasteboard cylinder has caused said con nect-ions to become loosened; In manufacturing'these (leviccsinlarge numbers it is practically impossible to carefully inspect each for defects in the joints between the cylinders and the cover members and although great care is exercised to make these joints sufficiently strong to withstand the strains mentioned yet (lGfQClLIVG oints frequently occur and because of the strains to which they are subjected quicklydevelop a positive failure when the device is placed in use or subjected to theshocks and jars ordinarily experienced.

The arrangement ofthe cushion 22 inthe manner described provides the necessary resiliency of, grip between the cover] members and the rod and holds the r-0d against rattling or moven' ent with little or no howing ofsthe cover members, and thus avoids theexcessivestrains upon the, connections Between the cover members and the cylineI'S g q i In the modification Fig. 3 the structure is the same asyherein above described except thatin this instance the rod 15 of Fig. 1 takes the form oil? a small tube 23 slidably mounted? directly upon the rod 5 and within the bearing openingi liofvthe head G. Itsopposite ends are provided with shoulders 17 and'l8 as before and its operation for controllingthe movements of the valve H are identical as already described with respect to the rod 15. l i i v v c As many changes could be made in this constructionwithout departing from the a scope of the invention flSCli-Bfillltll'l in thefoli lowing claims, it is: intended that all matter contained in the above description or shown in the acconumnyiiig drawings, shall be in terpretcdas illustrative onlyand not in a limitin r sense. c
